hex string into binary format?

[Tertius Cronje]

Hi, 

How do I get a hexvalued string to a format recognized for binary
calculation?


import binascii
s1 = '1C46BE3D9F6AA820'
s2 = '8667B5236D89CD46'

i1 = binascii.unhexlify(s1)
i2 = binascii.unhexlify(s2)
x = i1 ^i2

	TypeError: unsupported operand type(s) for ^: 'str' and 'str'

Many TIA
T
